Title: Electrostatic image consecutive photographing method
Inventor: TAKANO ATSUSHI
IPC: G03G15/18
Filed: 1990-07-12
Abstract: PURPOSE:To obtain a high-definition electrostatic image even if consecutive photographing is carried out by removing a residual charge on the surface of a photosensitive body, after a voltage application exposure is carried out, or carrying out the next voltage application exposure after uniform electrification is carried out to erase an after-image. CONSTITUTION:A film-like charge holding medium 22 is opposed to the photosensitive body 10, the voltage application exposure is carried out, and the charge of a polarity corresponding to image forming conditions is electrified on the surface of a photoconductive layer 13. Before the next voltage application exposure is carried out, a switch 31 is turned off in a state where the photosensitive body 10 is separated from a film 20 by a prescribed distance, and an overall uniform exposure is carried out from the side of the photosensitive body 10. The photoconductive layer 13 has conductivity, and a surface charge is combined with a carrier inside the photoconductive layer or leaked, and extinguished. On the other hand, a voltage is not applied between the photosensitive body and the film 20, so that discharging does not occur between them, and the side of the film 20 is not affected by an uniform exposure.

Title: Key switch of small-size electric equipment
Inventor: YOKOTA REI
IPC: H01H13/14
Filed: 1989-07-18
Abstract: PURPOSE:To make it possible to accurately push only one of key-tops without enlarging the intervals of key tops by making the height to the top panel of the key top from the surface of the electric equipment at the lower side of the top panel of the key top greater than that at the upper side thereof. CONSTITUTION:The top panel is formed with a gradient such that the height from the surface of the electric equipment to the top panel of a key top 4 is higher at the lower side of the top panel of the key top 4 than at the upper side thereof. When the key top 4 is pushed by a finger tip, therefor, the inclination of the finger tip is corrected as the top panel of the key top 4 is inclined and the finger tip pushes at an angle where it can hardly approach the lower part of a key top 5. Thereby, a rubber switch 41 is pushed down and the conductive rubber 43 of the rubber switch 41 comes into contact with a printed substrate 6 and the heteropolar pattern on the printed substrate 6 is short circuited; then, the switch is ON. Thus, it is possible to push in only key switch at the upper side with a simple constitution even though the key tops are arranged so close upward and downward as 2 top keys touch the finger tip at the same time.

IPC: H04M3/42
Filed: 1987-07-29
Abstract: PURPOSE:To allow a caller to dial a subscriber address used by a caller itself by allowing the caller to connect to a subscriber address having a terminal set used in registering its ow identification code by sending an individual identification code of a called party to an exchange. CONSTITUTION:When a person dials a called party, a connection command including a connection instruction code and an identification code of a called party is sent from a subscriber terminal to a subscriber circuit device. The subscriber circuit device adds the subscriber address to the connection command and sends the result to a controller. In this case, the controller 131, in confirming the connection command, uses identification code to search a correspondence table 161 between the identification code in the storage device 151 and the subscriber address. When the identification code exists in the table 161, the subscriber address is decided to execute the connection processing. Thus, the caller can call the called party having only to know the identification code of the called party.
